No hot water
There are plenty of reasons why a a electric or gas hot water heater stops working. To name a few, a thermostat may have failed, gas control valve or element has deteriorated or worn-out.
Hot water heaters may stop working due to a number of reasons, and it is highly recommended to contact a plumber who is trained in troubleshooting to find the cause why a hot water heater has stopped producing hot water to your taps within your home.
The tank may be cracked, leaking and have a pool of water around the system
A ruptured hot water heater can cause water to exit the cylinder and flood the area around the tank and leak onto electrical components or a gas burner. Its best to get onto leaking hot water heaters sooner than later to prevent further damage which can also prolong the life of the unit, as small leaks can turn into big costs if left untouched.
Water leaking through connections on the tank
Loose or unsealed connections on a hot water heater may leak and cause damage to hot water systems. Normally these connections can be easily fixed depending on the location of the leak. Best to address these leaks with a sense of urgency as the cost of fixing these can be a lot less than replacing the hot water heater itself.
Your heating costs have increased
In gas or electric storage hot water heaters, components like a thermostat and pilot light in gas systems can consume more gas than required, or things like elements in electric hot water heater may draw more power than required which would suggest that these components are faulty or malfunctioning, this can cause the use of excessive gas or electricity to be used and in turn cause high energy bills.
You may also be experiencing higher bills if solar panels on your gas or electric hot water system are not working correctly, this causes the cost of heating the water to increase. Additionally, blocked solar panels and piping can also contribute to costs of heating water to skyrocket.
Water is lukewarm coming through taps
Conventional gas or electric storage tanks that use gas control valves or elements and thermostats on electric systems that heat up the water within the tank may not be allowing the water to heat to a proper temperature.
The thermostat, which monitors the unit’s temperature may not be working correctly, be faulty, or have been improperly installed.
Possibly, sediment is preventing the heating components from functioning properly in the hot water heater storage cylinder
For continues flow gas hot waters that only supply luke warm water may have internal electrical faults with thermistors, heating components or setting temperature set incorrectly
The hot water heater may need to be replaced because it is nearing the end of its life
The power has tripped which is not allowing power to the hot water heater
If your circuit breaker has tripped, this may be due to a fault with the hot water heater. It may be a faulty thermostat or element which needs replacement or repair.
In some cases the wiring between the circuit breaker and the hot water may be old and need upgrading
Mice or vermin may have eaten through the insulations of the wiring and caused the power to trip.
Faulty installation of the hot water heater or wiring can also cause this to happen.
Running out or low hot water volume
Incorrect electrical tariff setting on timer may cause a electric hot water unit not to heat at the correct times to allow to store to maximin amount of hot water at the times when it is most needed throughout the day.
A result of a gas hot water heating not producing the correct or desired hot water temperature through taps within a property could be a result of incorrect thermostat setting on a gas control valve. This can be easily resolved by settling the valve or temperature controller to the desired and complaint gas settings
Water goes hot and cold in shower.
Having more water pressure either from the hot or cold water pipes can be a big playing factor when it comes to the temperature of water flowing through taps. More cold or hot water pressure can override the one or the other, this is felt more so in showers as the temperature can be observed more.
A faulty or old hot water heater can cause this to be a problem. As time goes on some hot water heaters can’t produce a consistent flow of hot water.
Blocked shower outlet and faulty taps can be a contribute if not be the main reason why water goes hot and cold.
A faulty valve on either the hot or cold piping may be causing the inconsistency of flow and pressure.
Incorrect hot or cold pipe sizing or incorrect hot water installation can also be the reason behind your water going hot and cold.
The age of the hot water heater
With worn and aged components, old hot water heaters may not operate as intended, requiring parts to be repaired or the heater itself to be replaced.
Some hot water units can last longer than others if the unit has been well looked after and serviced and checked regularly.
The amount of time a unit has been in use can also cause it to need more maintenance and repairs as some units may have had a harder working life than others.
Rusty or discoloured water coming through taps
If you have brown or rusty coloured water coming through your hot taps this could be due to old piping or sediment may have entered through the council/government piping. Draining and flushing the hot water heater may improve this however can be a lengthy exercise depending on the amount.
Noisy or hammering coming from hot water heater
Hammering, crackling, knocking and popping hot water heaters may be in need to repair or replacement depending on the root cause the sound.
Sediment around an element within a hot water heater can cause this sound to occur when the element is active and heating the water.
Expansion and contraction can cause hot water tanks to make a crackling or kettleing sound as the unit heats and cools.
Faulty hot taps that are turned off and on can cause hydraulic shock within the piping and resonate through a electric or gas hot water heater.
Water leaking through access cover panel.
Its suggested that water leaking through a gas or electrical hot water heater is not normal. This would suggest there is a fault within the hot water heater and more than likely the unit will need to be replaced or repaired.
Once water has been seen leaking through a hot water heater its best to isolate the gas and electrical power to keep things safe and then plumber who is qualified to work on these type of hot water systems.
